An American hedge-fund manager in his forties—tall, tanned, athletic—recently bought two houses in New Zealand and acquired local residency. He agreed to tell me about his thinking, if I would not publish his name. Brought up on the East Coast, he said, over coffee, that he expects America to face at least a decade of political turmoil, including racial tension, polarization, and a rapidly aging population. “The country has turned into the New York area, the California area, and then everyone else is wildly different in the middle,” he said. He worries that the economy will suffer if Washington scrambles to fund Social Security and Medicare for people who need it. “Do you default on that obligation? Or do you print more money to give to them? What does that do to the value of the dollar? It’s not a next-year problem, but it’s not fifty years away, either.”
Untold numbers of people wind up suffering frostbite, shock or hypothermia every year because they didn’t have adequate survival gear when the weather on their wilderness adventure took a rapid turn for the worse. But it doesn’t have to be that way. The Titan 2-sided Mylar Survival Blanket is light as a feather and yet capable of retaining up to 90% of your body heat.

Here in the Pacific Northwest, the smell of woodsmoke is in the air and fall is prodding us into preparations for the snow that’s sure to be here before we know it. The rural communities are finalizing their firewood stockpiles and getting propane tanks topped off to last the long winter ahead. With colder temps in the forecast, most of us are getting our yards cleaned up and ready for the approaching winter months.

People who are not part of survivalist groups or apolitically oriented religious groups also make preparations for emergencies. This can include (depending on the location) preparing for earthquakes, floods, power outages, blizzards, avalanches, wildfires, terrorist attacks, nuclear power plant accidents, hazardous material spills, tornadoes, and hurricanes. These preparations can be as simple as following Red Cross and U.S. Federal Emergency Management Agency (FEMA) recommendations by keeping a first aid kit, shovel, and extra clothes in the car, or by maintaining a small kit of emergency supplies, containing emergency food, water, a space blanket, and other essentials.
The fears were different in Silicon Valley. Around the same time that Huffman, on Reddit, was watching the advance of the financial crisis, Justin Kan heard the first inklings of survivalism among his peers. Kan co-founded Twitch, a gaming network that was later sold to Amazon for nearly a billion dollars. “Some of my friends were, like, ‘The breakdown of society is imminent. We should stockpile food,’ ” he said. “I tried to. But then we got a couple of bags of rice and five cans of tomatoes. We would have been dead if there was actually a real problem.” I asked Kan what his prepping friends had in common. “Lots of money and resources,” he said. “What are the other things I can worry about and prepare for? It’s like insurance.”
Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).

I called a Silicon Valley sage, Stewart Brand, the author and entrepreneur whom Steve Jobs credited as an inspiration. In the sixties and seventies, Brand’s “Whole Earth Catalog” attracted a cult following, with its mixture of hippie and techie advice. (The motto: “We are as gods and might as well get good at it.”) Brand told me that he explored survivalism in the seventies, but not for long. “Generally, I find the idea that ‘Oh, my God, the world’s all going to fall apart’ strange,” he said.

For a time in the 1970s, the terms survivalist and retreater were used interchangeably. While the term retreater eventually fell into disuse, many who subscribed to it saw retreating as the more rational approach to conflict-avoidance and remote "invisibility". Survivalism, on the other hand, tended to take on a more media-sensationalized, combative, "shoot-it-out-with-the-looters" image.[9]
Preparing for an emergency is different for every family. Naturally, buying nutrient-rich foods and having ways to store and purify water is the first step for everyone. After that first step, deciding what type of supplies and gear to focus on is a personal journey depending on your preparedness goals. Think of your emergency supply as an investment in the health and safety of your family during a crisis.
Why do our dystopian urges emerge at certain moments and not others? Doomsday—as a prophecy, a literary genre, and a business opportunity—is never static; it evolves with our anxieties. The earliest Puritan settlers saw in the awe-inspiring bounty of the American wilderness the prospect of both apocalypse and paradise. When, in May of 1780, sudden darkness settled on New England, farmers perceived it as a cataclysm heralding the return of Christ. (In fact, the darkness was caused by enormous wildfires in Ontario.) D. H. Lawrence diagnosed a specific strain of American dread. “Doom! Doom! Doom!” he wrote in 1923. “Something seems to whisper it in the very dark trees of America.”
he bald snow tires on my ’06 Accord struggled to achieve the grip needed to summit Len Pense’s long, steep driveway. If the grid goes down the way he thinks it will, you’d need a tank to ascend the eroding gravel path because the 83-year-old Army veteran knows exactly which oak tree he’d fell across the route, lest the marauders come for his cache of, among many other things, 44 raised-bed gardens of food. One way in, one way out; that’s what sold Pense and his wife on the 21-acre hilltop property in Strafford some 25 years ago.
Remember 2012? The Mayan calendar predicted the world would end in December. Doomsday Preppers premiered in February. The country was in an apocalypse mood, and thanks to Finelli, Springfield’s former Boy Scouts and ex–Tea Partiers came out of the shadows to mix it up with doctors and dentists. They had little else in common, but to borrow Finelli’s term, they were preparedness-minded. Springfield, MIss community was born.

When I started putting together my first survival kit, I just collected whatever weird stuff I could find—like tablets that would protect my thyroid from nuclear fallout. My mindset changed when my first daughter was born. I realized I needed a more practical end-of-the-world plan, with equipment that would be useful for things that might actually happen. Nuclear war is probably not in store for 2018, and if it is, I’ll just open a window. I don’t want to live through that.
